The owner of an outdoor gear retailer based in Columbia City is accused of selling counterfeit Leopold rifle scopes that he allegedly imported from China.

Mark Aaron Culp, founder and owner of CulMar Outdoors, made his first appearance in U.S. District Court in Portland Tuesday afternoon, accused of trafficking in counterfeit goods.

Assistant federal public defender C. Renee Mares entered a not guilty plea on his behalf.

The one-count indictment alleges Culp, 56, sold rife scopes bearing the Leupold brand name and the company’s “Gold Ring’’ design from May through July 2015.

According to federal investigators, Culp sold the counterfeit scopes to buyers across the United States, through his company’s website and through third-party sites, including the website www.gunbroker. com and eBay.

He made $3,728.50 in sales of the counterfeit rifle scopes to buyers in New York, Connecticut, California, Texas, Florida and Indiana, according to court records.

Leupold & Stevens, Inc. has its headquarters in Beaverton and specializes in high-quality optics for sporting, shooting, and military applications and makes rifle scopes, range finders, binoculars and thermal sensors.

Culp was arrested at his home Monday night on an arrest warrant, after an effort to reach a plea agreement pre-indictment fell apart, according to court records.

He appeared briefly Tuesday before U.S. Magistrate Judge John V. Acosta, and was ordered to be released from custody, pending trial. The judge also ordered Culp not to possess or sell firearms while the case is pending.
